1. Girma is a senor college student. He owns a car that has a market value of 600,000 birr. He also has different personal properties in his rented home. He wears disposable contact lenses which costs him 900 birr every year. Moreover, he runs every day for 30 minutes in a nearby public park that has a track record of being dangerous because of drug dealers and purse-snatchings. His parents are working hard to support his tuition fee.

If Girma potentially faces the following risks, which risk handling tools will be the appropriate? Explain your answer appropriately

• Physical damage to his car because of collision with another car
• Liability lawsuit against him because of negligent operation of his car
• Total loss of his personal properties because of fire
• Disappearance of his disposable contact lenses
• Physical assault on Girma by drug dealers in the area where he runs
• Loss of tuition fee helps because his father is killed by a drunk driver in car accident.

At 28.5°C, an aluminum ring has aninner diameter of 9.0000 cm andabrass rod has a diameter of 9.0500cm. If only the ringis heated, what temperature must itreach so that it will just slipover the rod?

A brass ring of diameter 10.00 cm at is heated and slipped over an aluminum rod of diameter 10.01 cm at . Assuming the average coefficients of linear expansion are constant (a) to what temperature must the combination be cooled to separate the two metals? Is that temperature attainable? (b) What if the aluminum rod were 10.02 cm in diameter?

Ok so, I need help in my Modern Physics class! My issue with these problems is not the math behind it, it is figuring out where to start and with what equations. One of my assigned problems, "A brass ring of diamter 10.00 cm at 20.0C is heated and slipped over an aluminum rod of diamter 10.01 cm at 20.0C. Assuming the average coefficients of linear expansion are constant, (a) to what temperature must this combination be cooled to separate them? Is this attainable? (b) What If? What if the aluminum rod were 10.02 cm in diameter." For some reason, I have no clue where to start... Also, this problem was assigned on paper, not in a text book.

Lists, Tuples, and Sets in Python

Tuples vs Sets

Tuples:

Ordered collection of objects, allow duplicate values

Immutable (can't be changed after creation)

Example of Tuples:

my_tuple = ("apple", "banana", "cherry", "apple")

Sets:

Unordered collection of unique objects

Mutable (can be changed after creation)

Example of Sets:

my_set = {"apple", "banana", "cherry"}

Lists, Tuples, and Sets

Lists:

Ordered collection of objects, allow duplicate values

Mutable (can be changed after creation)

Example of Lists:

my_list = ["apple", "banana", "cherry", "apple"]

Tuples and their Immutability:

Tuples are immutable, meaning that once they are created, their values cannot be changed.

Useful for data that should not be altered.

Tuples use less memory than lists.

Sets and their Uniqueness:

Sets are unordered collections with no duplicate elements.

Good for finding unique elements of a larger collection.

Sets can do fast membership tests (O(1)).

That's it! These notes summarize the main differences between Lists, Tuples, and Sets in Python, and cover Tuples vs Sets in more detail.

Tuples vs Sets in Python

Lists, Tuples, and Sets

In Python, we have several data structures available for organizing and storing data. Three of the most common are:

Lists

Tuples

Sets

Key Differences

Tuples and Sets each have their unique properties that make them different from Lists and from each other.

Tuples and their Immutability

Tuples are ordered, immutable sequences of elements, which can be of any data type. Once a Tuple is created, it cannot be modified.

Here is an example of creating a Tuple:

my_tuple = (1, 'apple', 3.14)

Accessing Tuple Elements

To access elements in a Tuple, use indexing, just like Lists:

print(my_tuple[1]) # Output: 'apple'

Sets and their Uniqueness

Sets are unordered collections of unique elements. They can only contain unique elements, and duplicates are discarded. Sets are useful when you want to ensure that there are no duplicate items or when you need to quickly perform set operations like union, intersection, or difference.

Here is an example of creating a Set:

my_set = {1, 2, 3, 3, 3, 'apple', 'apple'}

print(my_set) # Output: {1, 2, 3, 'apple'}

In the example above, note that 'apple' is only printed once, and the number '3' only appears once as well.

Accessing Set Elements

To access elements in a Set, you need to convert it to a List or iterate over it, since sets are unordered collections and do not support indexing.

my_list = list(my_set)

print(my_list[0]) # Output (unpredictable): 1 or 2 or 3

Advantages of Tuples

Immutable: Cannot be changed after being created.

Efficient: Since Tuples cannot change, Python does not have to create a new object when an element is changed, making Tuples faster to access in certain cases.

Used in function arguments when you know the values should not be changed.

Advantages of Sets

Unique items only.

Efficient for set operations.

Fast membership test thanks to the hash table data structure used by sets.

Common Operations

| Operation | Lists | Tuples | Sets | | ------------ | -------- | ------ | ------ | | Index access | Support | Support | Not supported | | Append | Support | Not supported | Not supported | | Insert | Support | Not supported | Not supported | | Remove | Support | Not supported | Support through discarding duplicates | | Membership | Support | Support | Support |

When to use what?

Use Tuples when the data should not change, and you require fast access to elements.

Use Sets if you need to check for membership, quickly find intersections, unions, and differences, or if you need an unordered data structure with unique items.

Use Lists if the data may be changed, and you need consistent order.

In a 200 words or less explain the differences between SQL and PL/SQL? Why do we need SQL in a procedural language?

2. Respond to the following in 100 words-APA Format and Cite work

SA

SQL, is a structured query language that is used to retrieve and manipulate data as well as create and modify objects in a database. There are some capabilities for logic in SQL statements such as case and decode statements, but it is very limited. PL/SQL is a procedural language that has many more logic options available such as if-else statements and for loops. However, PL/SQL isn't very useful without SQL to retrieve and manipulate the data. For instance, you can use SQL to retrieve a value from a table and based on the value; use an if-else statement to choose to update a value in another table or not. PL/SQL also has a few other features that make it more efficient than just SQL alone. One being that PL/SQL transmits multiple SQL statements at one time in a block whereas SQL sends each statement separately thus saving bandwidth. Another is that PL/SQL that is stored in the database as a program unit is stored in executable form and is cached in memory making it more efficient to run (Casteel, 2013, pp. 3-4).
